Abstract
We have applied microindentation to a series poly(ether-ether-ketone) films crystallized at different temperatures from the melt and from the glass to measure their microhardness. The morphology of the samples was characterized by X-ray diffraction, density measurements and differential scanning calorimetry. The results show that a relationship between microhardness, density and degree of crystallinity can be established for samples crystallized at various temperatures from both the glass and the melt. The values of the microhardness of the crystalline component of the samples can be correlated with the lamellar thickness of the polymer crystals.
